SUMMARY

In accordance with the first aspect of the present invention, there is provided a tool that includes two or more clamping aids for use with common hand tools such as—carpenter squares, framing squares, speed squares, straight edges, rulers and the like. Each damping aid comprising a body, and one or more elongate slots that is open along the bottom flat edge surface for mounting to these common tools. The slot heights can be 1, 1.5 or 2 inch or any combination of these sizes. The damping aids include threaded holes on either side of the tool with mounting screws for clamping or securing to any one of the previous mentioned common tools within the tool's slot, for creating a jig. Each damping aid includes a flat bottom edge surface, and a V groove top edge surface, for mounting and securing to flat or round objects, respectively. Both edge surfaces can include various types of magnets, and thus the clamping aids can secure to various objects or materials that are flat and/or round, magnetic or not. The clamping aids can also include one or more spirit vials to assist in aligning and securing these various objects and/or materials together at various angles. Each clamping aid includes a rounded end and a flat end. A further perpendicular slot inline with the elongate main slot is included in the flat end of each clamping aid for creating a Tri square with clamping aid and a combination square with the other damping aid when used with one of the common tools mentioned above. A recessed slot or cutout is located along one side of the clamping aid with use with a straight edge to form a tool known as a T square.

In accordance with a second aspect of the present invention, there is provided a combination of two clamping aids as above, that includes a pivot in the rounded end In each clamping aid, pivotally connecting the two clamping aids with mounting hardware, to form a multi-function angle finder, and whereby in use, each tool can be mounted to one of a ruler, straight edge and/or various squares to form a variable and/or extendable angle finder to measure or align objects or materials at correct angles. The damping aid can include a 360 degree scale when measuring an angle and can be tighten and locked in position, or can include a locking mechanism to lock the tool in any one of a predetermined set of angles using the appropriate locking hole.

A spring loaded devise can be used in addition to the clamping screws to secure the clamping aid tools to the various squares, straight edges, rulers, or the like.

In accordance with a further aspect of the present invention, two versions of component brackets with rows of mounting holes spaced ½ inch apart can be mounted to each clamping aid at different heights and/or positions, to correspond to various dimensions of the common tools previously mentioned. The −dimensions correspond to the legs of a carpenter and/or framing square, with dimensions of 1 inch by 1.5 inches, and 1.5 inches by 2 inches, respectively, or with straight edges and rulers with these dimensions. The two component brackets include a flange or multiple flanges for use with hand clamps to clamps these clamping aids mounted to these common tools more easily to various materials being fitted and/or secured together. The first component bracket includes a side flange joined to two perpendicular end flanges. Each end flange contains a V groove and when the bracket is mounted and secured to each clamping aid, a second V groove surface is provided that is perpendicular to the top edge surface V groove of the clamping aid, for added versatility in aligning and securing round objects together in different arrangements, including in a vertical or horizontal position. The second component bracket is L shaped and includes rows of mounting holes spaced ½ inch apart on both surfaces and can be mounted and secured to each clamping aid in various arrangements, heights or position and can also provide a closed or covered bottom edge surface along the main elongate slot(s). In a further embodiment a clamping aid can include a built-in first component bracket with multiple slots and can be open and/or closed along the bottom edge surface.

In accordance with a third aspect of the clamping aids of the present invention, two or more clamping aids are provided, each containing at least two slots that correspond to common dimensions and use with a carpenter square, framing square, straight edge, and/or ruler. The second slot allows for extending the length of the Jig, by using additional squares and/or straight edges in the second slot of each clamping aid, coupled—with a second set of clamping aids. A ½ inch sleeve insert is provided for each clamping aid to adjust for different heights and dimensions of the common tools previously mentioned.

In accordance with a further aspect of the present invention, there is provided a triangular square to be used in conjunction with the clamping aids previously mentioned, to ensure a more reliable and accurate 90 degree angle, compared to a carpenter or framing square. A carpenter or framing square requires more care and can become out of square, especially if dropped one time too many, and requires periodic checking, which may need to be corrected or replaced. In addition, the triangular square provides for the use of a 45 degree angle, and the main body includes mounting holes that align and secure to the previously mentioned clamping aids and/or component brackets mounting holes to further ensure accurate position of the clamping aids. The alignment of mounting holes between these damping aids, component brackets and triangular square, allow for Interchangeable use and can create new tools, including a welders magnet or a corner clamp just to name a few. The slot width of the clamping aids matches the thickness of the triangular square body. When one clamping aid is mounted to the triangular square, a speed square function or tool is formed with added features, and when a second clamping aid is mounted, a welders magnet tool is formed. A first component bracket can be mounted to each clamping aid and the extra slot(s) in each clamping aid mounted to the triangular square, allows the length of the jig to be extended by coupling with further clamping aids with the use of various straight edges, and/or squares, etc. This combination further increases the accuracy of the 45 or 90 degree angle of the materials being assembled and/or secured. The triangular square corresponds with one of the main aspects of the present invention, that of providing a clamping means but also providing increased accuracy compared to a carpenter or framing square. The longer the jig, the more accurate or square the measurement or assembly will be.

In accordance with a further aspect of the present invention there is provided a speed square. The square comprising a generally triangular portion, and a flange secured to the triangular portion on one edge, perpendicularly thereto and extending on both sides of the triangular portion. One portion of the flange surface area is extra wide for ease of clamping of the speed square. The bottom of the flange contains a “V” groove with magnets for securing and aligning a round pipe or the like, in accordance with the present Invention. Slots are included in the flange adjacent to the triangular portion and also in the main body, to permit passage and securing of band strapping. A triangular square previously mentioned in combination with the previously mentioned clamping aids and/or component brackets of the invention can create a conventional speed square but with extra features. Clamping aids can function with either speed square (conventional or as in the present invention), but the triangular square of the present invention adds more versatility and increases accuracy.

Again, a carpenter or framing square if dropped may become out of square and may need adjusting or may need to be replaced. A triangular square of the present invention is more versatile to ensure accuracy. In accordance with another aspect of the present invention, there is provided a hand clamp adapted for use with the clamping aids previously mentioned to help assist in clamping a jig to various materials. Various common hand clamps would be required regardless, to clamp the jig to various materials. The clamp includes two bracket elements with pivot, pivotally attached to the hand clamp arms or jaws, and each include mounting holes to mount to the clamping aids for increased ease and versatility.

In a further embodiment of the present invention, the hand clamp and clamping elements with pivot and mounting holes can include built-in slots of various heights and widths, to correspond with dimensions of a carpenter and framing square in accordance with the present Invention. Various hand clamps, including locking “C” clamps, regular “C” clamps and bar clamps can be adapted with this feature.

In a further embodiment of the present invention, there is a kit consisting of four clamping aids, a triangular square, and four component brackets that can be made of various sizes for aligning various size objects or materials.

In a further embodiment of the present invention, there is a carpenter or framing square that can include mounting holes that align with mounting holes of the clamping aid tools and component brackets. In a further embodiment of the present invention, there is an L square with mounting holes and the second component bracket mounted to it, used together to form a shelf bracket for hanging shelves.
